It comprises blood, heart and blood vessels. The system supplies nutrients to and remove waste products from various tissue of body. The conveying media is liquid in form of blood which flows in close tubular system. Blood vessels that carry blood away from the heart are called arteries.
5 Major Functions of the Circulatory (Cardiovascular) System Transports oxygen to cells and collects carbon dioxide back. Transports nutrient and Transports waste product. Protection; white blood cells protect against disease by phagocytosis, antibodies, interferons, and complement.
Closed Circulatory System • Heart pumps blood in large arteries away from your heart. Diffusion occurs in tiny capillaries. Blood returns to heart in large veins. • Large vessels for bulk transport fast flow (2-4 cm/sec) large diameter (10-12 mm diameter) thick walls (muscular) • Capillaries for diffusion Slow flow (<1 mm/sec)
• Circulatory system comprises of the heart, blood and blood vessels which circulate blood throughout the body, helping in the transport of nutrients, oxygen and carbon dioxide.
System of veins is often called a low pressure system due to its function as a blood reservoir. Apart from its blood reservoir function, blood flows back to the heart through veins.
• Describe an open and closed circulatory system • Describe interstitial fluid and hemolymph • Compare and contrast the organization and evolution of the vertebrate circulatory system
The circulatory system is the transport system of the body and provides the means by which materials are transported around the body. Within the system, the blood is the transport medium and is confined to tubes (therefore it is a closed system). …
In this lesson students will learn the basic functioning of the heart, Circulatory System and blood, the connection to lung functioning, and the activity of the Circulatory System in the body. Students will be able to identify their heart rate and measure it at rest and after activity.
The circulatory system carries digested food substances to the cells of the body. These nutrients enter the bloodstream by passing through the walls of the small intestine into the capillaries.

The circulatory system is effectively a network of cylindrical vessels: the arteries, veins, and capillaries that emanate from a pump, the heart. In all vertebrate organisms, as well as some invertebrates, this is a closed-loop system, in which the blood is not free in a cavity.
